Once there was a champion sword fighter who decided to build a fence around his place. He went to a lumber store to get wood for a nice picket fence, then he set it all up and whitewashed it. Then one day he got a court summons. It turned out the lumber he bought was stolen, and then sold to the lumberyard. In court he swore he had no idea the lumber was stolen, and if he knew he would never have bought it.
After hearing his testimony, the judge said: "What we have here is a fencer taking offense at a fence built from materials that were fenced!"
